Hydrotalcite-derived Ni-Co/Mg(Al)O catalysts with a range of different Ni-Co ratios, Ni+Co loading, calcination temperatures and noble metal promotion (Pt/Pd/Rh) were prepared, targeting low-coking steam reforming of biomass gasification tar impurities. Fresh catalysts were characterized by XRD, ICP...

Many companies offer similarly designed wireline tools using ultrasonic pulse-echo measurements toevaluate barrier integrity in cased-hole wells. While these tools provide very similar data, differentcompanies process their data using different algorithms, typically to estimate the pipe wall...

Pulse echo measurements are used to investigate the conditions on the outside of an oil or gas pipe by sending ultrasound pulses onto the pipe wall from inside the pipe that reverberate within the pipe wall. A range of different algorithms are used today to analyse this data and derive pipe-wall...

The virtual integration of geographically distributed Research Infrastructures (RIs) for joint experiments in the domain of power and energy systems poses numerous challenges, particularly in terms of tool compatibility and user-friendliness. To address some of these challenges, this work presents...

Process simulation was integrated with life cycle assessment to evaluate process efficiency and environmental impact of the production of manganese ferroalloys for various production modes and different ore mineralogies. Utilizing HSC Sim, the model was designed to evaluate the production process...

Study region Eight rivers in Slovenia and Croatia that are tributaries of the Danube River or the Adriatic Sea Study focus The different types of hydropower plants alter river hydrology at several temporal scales and to a varying degree, respectively, but impacts have hardly been quantified in...

The adoption of more electric vehicles (EVs) is going to pose some challenges for the grid due to the increase in demand for high-power charging. These issues will get further exacerbated with energy production moving from synchronous machines towards renewable energy sources (RES) with low inertia...
